Querying via the REST API

The ORR repository REST API includes a GET /ont operation that allows to retrieve ontology information from the repository according to ontology metadata, various registration properties, and privileges of the requesting user. The details of this operation can be found at the corresponding API documentation page of the relevant ORR instance. (MMI ORR example: https://mmisw.org/ontapi/#!/ontology/get_ont).

The most complete and powerful semantic search mechanism is through the SPARQL endpoint, see the SPARQL API section.

The ORR REST API, however, also includes a GET /term operation that allows to perform some common term queries via a somewhat simpler interface. The details of this operation can be found at the corresponding API documentation page of the relevant ORR instance. (MMI ORR example: https://mmisw.org/ontapi/#!/term/get_term).
